After years of debate, the latest animal testing statistics still show a hard split between regulation on paper and what happens in labs. In 2025, large numbers of animals are reported used across toxicity, safety, and biomedical research, even as alternatives and bans expand unevenly. When you line those figures up side by side by purpose and country, the scale and direction of change start to look far more complicated than most headlines suggest.
